TUNING-PEG FOR MUSICAL STRING INSTRUMENTS.

To all whom it may concern:

Be it known that I, EwALD GLAEsEL, a subject of the German Emperor, and a resident of Markneukirchen, Saxony, Germany, have invented new and useful Improvements in Tuning Pegs for Musical String Instruments, of which the following is a specification.

The invention relates to improvements of the mechanism on string instruments, by means of which the axle (around which the string is to be wound) and the cog-wheel of a screw and wheel gear can be connected or disconnected by moving or shifting a tap in or out of a recess of the cog-wheel. The disconnection of the cog-wheel and axle enables the axle to be turned without the screw and gear. This is of great advantage in case a string is to renewed, as it would be tiresome to wind the string all the way by the gear.

In the accompanying drawing a form of construction is shown in Figure 1 in a top View. Fig. 2 shows a side view of the mechanism. Fig. 3 showsin side view a crosssection of a detail of the mechanism enlarged and Fig. 4 shows a top View of another form of construction enlarged.

The mechanism consists of the plate f, through which the axle a is guided. A cogwheel Z) is loose (not fixed) mounted upon the axle. A screw or spiral-wheel e engages with the cog-wheel. The axle a has on its one end a, which is of smaller diameter a head or button 0, which can slide upon this part a and which can be shifted along this axle a This'head or button is provided with a U-formed pin (l, the middle part of which slides in the groove a of the axle a This pin can be moved into a recess 6 of the cog-wheel b when the head is moved in Specification of Letters Patent.

the direction of the cog-wheel. A flange i is rigidly connected with the axle and arranged in the middle of said groove. This flange has a recess i opposite of the recess 5 In the form of construction shown in Fig. 4 the cog-wheel b is loosely mounted on axle a but it has sidewise a collar bearing b turnably mounted in the plate The mode of operation is the following: In case a string on the instrument is to be renewed, the cog-wheel and the axle is disconnected by drawing back the head or button a with its fixed pin d, which latter leaves the recess 11 of the cog-wheel Z), thereby entering in the recess 2' and thus enabling the axle a to be turned without the gear.

I claim:

In a musical string winding mechanism the combination of a plate (f) having a series of pivot-holes, a series of string winding axles (a, a pivoted in said holes, said axles havinglongitudinal grooves (a a series of flanges (6) each of them being rigidly connected with one of said axles (a, a and being arranged in the middle of said groove, said flanges having at their sides a radial recess i a head (0) slidingly mounted at the one end of said axle, a U-formed pin (cl) being rigidly connected at one end with said head, its middle part sliding in said groove (a and its free end protruding out of said groove, a cog wheel engaging with a screw (6) loosely mounted upon said axle and having at one side a recess (b adapted for the reception of the protruding free end of said pin ((Z).
